Day Master
Geng (庚, Yang Metal)
Your Day Master (日主) is the stem of your Day Pillar — the one character every other character of your chart is read against. This page unpacks one of the ten: Geng (庚, Yang Metal).
What this day master is
Yang Metal — the axe and the raw ore. Decisive and blunt, Geng is unafraid of conflict and values truth over comfort.
What it feels like at the center
With Geng (庚, Yang Metal) as your Day Master, the chart tends to read like this:
As Day Master, Geng cuts through — decisive, honest and at ease with conflict it believes is necessary.
The personality tint it tends to leave
In everyday life, a chart with this stem at its center often reads:
decisive, blunt, honest, unafraid of conflict
Reading Geng in practice
Geng day masters are the axe and the sword of the chart — Metal that cuts, decides and clears, with no patience for pretense. With Geng at the center, life tends to act by sharpness: you do best where courage, directness and final decisions are rewarded, and you cut through what softer people circle around. In career, Geng is built for front-line authority — surgery, law enforcement, engineering, management under pressure — and it is trusted because it says what it will do and then does it. In relationships, Geng is direct, protective and impatient with ambiguity: it loves fiercely and forgives slowly. The forging matters for a Geng chart: too much Fire melts the metal down, too much Water keeps the blade from its purpose, and the right heat with the right quench makes steel. The two charts below show Geng with opposite Da Yun directions — one sharpens the early chapters, the other tempers them slowly. Steel remembers every blow. Practical notes for a Geng chart: you are the blade, so keep your own whetstone — skill, discipline and a judge you trust, because a sharp blade needs a sharpening hand. In work, front-line authority suits you: surgery, law, engineering, management under fire; avoid roles built on ambiguity and politics. In health, the lungs and skin favor clean air and training; in relationships, beware the habit of cutting first — say the true word, then soften the landing. The two charts below show Geng with opposite Da Yun directions: one sharpens the early chapters, the other tempers them slowly. Steel is made by both; do not skip either.
In two real charts
Two charts cast by the same deterministic engine that builds yours — two people with Geng (庚, Yang Metal) as Day Master, born in different years, so their Da Yun run in opposite directions. Every pillar below is real; every label is computed. Cast your own chart and you get the same treatment.
